Investigation And Study On Soundscape Of Waterfall Scenic Area

Soundscape,as a new research field of architectural technology science,is different from traditional acoustics in that it increases people’s understanding and understanding of sound in a specific environment,and conducts research from the three perspectives of sound,environment and human evaluation.This article takes Huangguoshu Waterfall Scenic Area and Hukou Waterfall Scenic Area as the objects of investigation and research.The two waterfall scenic areas are researched by using relevant literature research,field investigation,acoustic measurement,on-site recording and recording analysis,questionnaire survey and statistical analysis.The soundscape was investigated and analyzed to compare the difference in soundscape between the two waterfall scenic spots,so as to explore the soundscape perception law of tourists in the waterfall scenic spot.The results showed that:(1)In the composition of the soundscapes of the two waterfall scenic areas,the number of unnatural soundscapes is far greater than the number of natural soundscapes;and the preference of tourists’ voices is: natural sound> social sound> mechanical sound;The effect of masking and reducing the surrounding noise;(2)In the acoustic measurement analysis,the equivalent continuous A sound level of the two waterfall scenic areas exceeded the limit of 55 d B(A)in the "Acoustic Environmental Quality Standard"(GB 3096-2008).The change in sound pressure level does not affect the tourists’ satisfaction with the waterfall scenic area;(3)In the subjective evaluation analysis of the soundscape,the two waterfall scenic areas have higher sound satisfaction evaluations,and they are in harmony with the sound and sound comfort And the overall environmental satisfaction evaluation is significantly related;(4)In the analysis of physical environment comfort evaluation,the acoustic environment and the light environment are significantly related and belong to the same principal component;(5)In the analysis of social behavior factors,the age and noise of tourists The degree of influence is positively correlated with the evaluation of acoustic satisfaction.According to the analysis of the above rules,some soundscape problems in the waterfall scenic area are found,so as to try to make some suggestions for the optimization of the soundscape of the waterfall scenic area:(1)Soundscape problems in waterfall scenic areas:there are noise problems,lack of distinctive soundscapes,and the theme is not prominent.(2)Recommendations for optimization of waterfall scenic areas: The optimization idea of "visitor perception" should be emphasized;reasonable use of natural soundscape resources in waterfall scenic areas;reasonable reduction of mechanical noise;excavation of local soundscapes with emphasis on "theme";providing humanized cool rest Area;establish a gradient plan for the sound sensitivity of scenic spots.In this paper,the research on the soundscape of waterfall scenic area plays an important role in further improving the soundscape quality of tourist scenic spots,and has practical application value for promoting and developing the development and construction of tourist scenic spots in China.
